Patent CA-2228334-A1 (CA)
Inventor: OVERBY LINWOOD HUGH
IPC: H04L12/56
Filed: 1998-01-30
Abstract: Transmission  control   improves   the  performance   in  a communications system relating to transferring large data objects between domains or applications.  This reduces or eliminates data movement  between  domains  by  transferring  ownership  of  the "container" containing the data as opposed to moving the contents of the container from one domain to another domain resulting in copying the large data object.  Thus, transmission control provides for control of the transmission of relatively large data objects between domains in a communications system which otherwise only allows efficient transmission of relatively small data objects between domains in a communications system.  Tokens are assigned and associated with buffers containing the data to be shared.  The token is not an address, but rather an identifier for the buffer which can be transferred from one domain to a second domain without requiring the copying of the data.  The domain which originally requests the buffer is assigned a primary token and secondary tokens are assigned to each subsequent domain which also requests access to the buffer.  A storage manager uniquely associates the buffer with the first domain and a primary token with the first buffer  to  permit  the  first  domain  to  refer  to  the  buffer. Secondary  tokens  are  associated  with  the  first  buffer  and subsequent domains also requesting the buffer.  Thus, the buffer can be passed from the first domain to subsequent domains without physically  moving  the  data.    Once  each  domain  is  finished processing the data and the buffer is released by each domain, the buffer is  released or reallocated and returned to a pool of available buffers.  Alternatively, ownership of the buffer may be returned to the original domain that requested the buffer once processing of the buffer is completed by all domains.

Abstract: Cet appareil (fig. 2) de mesure et son procédé d'utilisation (figure 5) permettent de déterminer de façon précise la profondeur du lard (14-20) recouvrant l'échine d'un animal (8), sans que celui-ci encoure un quelconque danger. Cet appareil comporte un système d'analyse du temps de retour, dans lequel un générateur (28) d'impulsions envoie, au moyen d'un transducteur (16) piézo-électrique, un signal d'entrée ultrasonore présélectionné, à travers l'épiderme (12) et successivement à travers chacune des interfaces (15, 17, 20) de lard de l'animal, jusqu'à un point déterminé se situant dans la portion de l'échine (22) de celui-ci. Ce système permet donc d'analyser le signal d'écho résultant, lequel est produit de manière séquentielle par le signal d'entrée, à partir de l'échine et dans le sens échine/couches (14, 16, 18) extérieures de lard. Le premier signal fort se situant dans une gamme spécifiée, laquelle est fonction de l'espèce, du type, de l'âge ou du poids de l'animal sur lequel on pratique ladite mesure, représente la première transition lard/échine. On utilise un microprocesseur (44) pour mesurer et analyser l'amplitude et le contour du signal se dirigeant vers l'échine, jusqu'à ce que celui-ci atteigne un point fixe correspondant à un pourcentage déterminé de la valeur de crête de l'amplitude du signal, cette amplitude étant fonction du type d'animal en cours de mesure. La valeur dérivée de cette manière constitue une mesure précise de la profondeur du lard recouvrant l'échine, laquelle mesure s'affiche automatiquement sur un écran (46), sous forme numérique.

IPC: B01D53/40
Filed: 1996-08-20
Abstract: A spray tower for removing acidic gases and particulate matter from flue gasses produced by processing operations of the type carried out in utility and industrial facilities. The spray tower is equipped with a tank (122) that serves as a reservoir for an alkaline slurry used to remove acidic gases and particulate matter from the flue gases. The slurry is pumped from the tank to spraying devices (118) located within the tower. The spray tower further includes an internal structure (134) that enables the slurry to be oxidized and gently agitated within a limited region of the tank, and without the requirement for two separate aeration and agitation devices. As a result, the construction, operational and maintenance costs of the spray tower are significantly reduced as compared to prior art spray towers.

Title: Novel methods for the characterization of compounds which stimulate stf-1 expression in pancreatic islet cells
Inventor: SHARMA SEEMA
IPC: C12Q1/6897
Filed: 1997-01-22
Abstract: The present invention provides two embodiments. One is a method of testing for compounds which may induce STF-1 transcription.  Pancreatic islet cells which express the STF-1/lacZ fusion gene are isolated and the effect of various compounds on STF-1 expression is measured by adding the compound of interest to STF-1/lacZ expressing cells.  LacZ activity in control and treated cells is then quantitated by a colorimetric assay. Using this method, a large number of compounds can be screened and STF-1 inducing compounds can be identified readily. The other is a method of using the STF-1 promoter to mark insulin producing pancreatic islet cells in vivo. In this regard, the green fluorescent protein (GFP) served as an indicator. The introduction of the STF-1-green fluorescent protein transgene into pigs allows for the efficient and rapid recovery of insulin producing cells from the pancreas.
